Did you have to clear the Gathering card type with Wizards?
The OP is from December 07, 2012. It's taken a while - with an intermission - but maybe people have just run out of questions.
I doubt it. but if you don't like this question or think it's not worth answering, go ahead and say so. I can take it. Or don't! I will get the idea from your silence. But I'm not sure what you are trying to say with this comment here. Like, I thought the question was reasonable; companies can get very defensive of their IP. I guess you disagree about its reasonableness. But don't let me ruin it for everyone else.
To me, it would make zero sense for someone to have to "clear the Gathering card type with Wizards." It's reality-defying. Thus I thought you were joking. Thus I thought, man. Seems like nothing but joke questions these days.
I do not believe it is possible, in the free world at least, to control a word in the way you suggest. To control something like that, I think it has to be coined (e.g. Kaladesh, Innistrad, etc.), and possibly then still needs a similar context.
